Abstract

Geographical analysis of epidemiologic data may be useful in modeling risk as a function of geographic covariates, testing hypotheses, mapping disease patterns, identifying areas of high risk, or detecting clusters. Distinctions are drawn between case dependence and independence (the latter not requiring a spatially correlated error structure), and between areal and continuous data. Various models are described, and attention is given to disease mapping (involving data smoothing) and clustering.
